  • blackberry implement audio player

    - by Prasad
    Hi, I am developing an application which let users to hear songs online. And I used Blackberry Player and Manager APIs. My application works fine and I can play songs. Now I wan't to add more controls to it. As an example I want pause, play songs. Mute the sound, Control the volume. Display the progress of the play back. Display the current time position of the song like that. I started research on that. And I tried to do that with PlayerListener. But unfortunately all the time I am getting IllegalStateException. So I can't go ahead with that research. As a help can someone please tell me how can I implement above kind of controls for a player. Appreciate if someone can post a sample code to do that. Further I will put my playback source code here. public void run() { try { p = Manager.createPlayer(requestedSong + SystemSettings.strNetwork); p.setLoopCount(1); p.start(); } catch (IOException ioe) { } catch (MediaException me) { } } public void run() { try { p = Manager.createPlayer(strSongURL); p.setLoopCount(1); p.start(); } catch (IOException ioe) { } catch (MediaException me) { } } Thank you very much.

  • Web form is not updating tables, why?

    - by JPJedi
    I have a web application and on page is an update page to update some profile information. Below is the code I am using to update the table. But I think it is wrong. Does anything stick out? The connection string works cause it is used to read the database to get the profile information, I just removed it due to it containing password/login info for the db. player is the class of properties that contains player information and ds is the dataset, but I would like to update the database itself online... Dim connectionString As String = "" Dim GigsterDBConnection As New System.Data.SqlClient.SqlConnection(connectionString) GigsterDBConnection.Open() Dim updatetoursql As String = "UPDATE PLAYERS SET FIRSTNAME = '" & player.FIRSTNAME & "', LASTNAME = '" & player.LASTNAME & "', ADDRESS = '" & player.ADDRESS & "', CITY = '" & player.CITY & "', ZIP = '" & player.ZIP & "', PHONE = '" & player.PHONE & "', EMAIL = '" & player.EMAIL & "', REFFEREDBY = '" & player.REFEREDBY & "' " updatetoursql = updatetoursql & "PLAYERID = '" & player.PLAYERID & "';" Dim cmd As New System.Data.SqlClient.SqlCommand(updatetoursql, GigsterDBConnection) Dim sqlAdapter As New System.Data.SqlClient.SqlDataAdapter(cmd) sqlAdapter.Update(ds, "PLAYERS") I think the issue is something the 3 last lines of the code. am I doing it right or is their a better way? Thanks

  • Inheritance of list-style-type property in Firefox (bug in Firebug?)

    - by Marcel Korpel
    Let's have a look at some comments on a page generated by Wordpress (it's not a site I maintain, I'm just wondering what's going on here). As these pages might disappear in the near future, I've put some screenshots online. Here's what I saw: Obviously, the list-item markers shouldn't be there. So I decided to look at the source using Firebug. As you can see, Firebug claims that the list-style property (containing none) is inherited from ol.commentlist. But if that's the case, why are the circle and the square visible? When checking the computed style, Firebug shows the list-style-types correctly. What's the correct behaviour? I just did a quick check in Chromium, whose Web Inspector gave a better view of reality (the list item markers were also displayed in this browser): According to WebKit, list-style of ol.commentlist isn't inherited, only the default value of list-style-type from the rendering engine. So, we may conclude that the output of both browsers is correct and that Firefox (Firebug) shows an incorrect representation of inherited styles. What does the CSS specification say? Inheritance will transfer the list-style values from OL and UL elements to LI elements. This is the recommended way to specify list style information. Not much about the inheritance of ol properties to uls. Is Firebug wrong in this respect? BTW, I managed to let the markers disappear by just changing line 312 of style.css to ol.commentlist, li.commentlist, ul.children { When also explicitly defining the list-style of ul.children to none, the markers are not painted. You can have a look at screenshots of Firebug and WebKit's Web Inspector in this case, if you like.

  • Emailing smtp with Python error

    I can't figure out why this isn't working. I'm trying to send an email from my school email address with this code I got online. The same code works for sending from my GMail address.

  • Managing/Storing complex application form

    - by mickyjtwin
    I am developing an online application form, which can be of two categories, either domestic/international. Each different type has commong questions, and also specific questions. They are approx 6 pages/steps of questions. The application form can also be saved at the end of each step, and can be completed at a later date. Some questions will vary depending on answers to previous questions, so there are some complex business rules. In terms of storage of results, would it be best to store the answers in and XML field in SQL? What would be the best way to reference a question to an answer. There is no need for the form to be dynamic in rendering questions etc. e.g. <Application id="123" type="Domestic"> <Answers> <EmailAddress>[email protected]</EmailAddress> <HomePhone>555-5555</HomePhone> <Suburb>MySuburb</Suburb> <Guardians> <Guardian type="Mother"> <FirstName>Mom</FirstName> </Guardian> </Guardians> <Answers> </Application>

  • setcontext and makecontext to call a generic function pointer

    - by Simone Margaritelli
    In another question i had the problem to port the code unsigned long stack[] = { 1, 23, 33, 43 }; /* save all the registers and the stack pointer */ unsigned long esp; asm __volatile__ ( "pusha" ); asm __volatile__ ( "mov %%esp, %0" :"=m" (esp)); for( i = 0; i < sizeof(stack); i++ ){ unsigned long val = stack[i]; asm __volatile__ ( "push %0" :: "m"(val) ); } unsigned long ret = function_pointer(); /* restore registers and stack pointer */ asm __volatile__ ( "mov %0, %%esp" :: "m" (esp) ); asm __volatile__ ( "popa" ); To a 64bit platform and many guys told me i should use the setcontext and makecontext functions set instead due to the calling conversion differences between 32 and 64 bits and portability issues. Well, i really can't find any useful documentation online, or at least not the kind i need to implement this, so, how can i use those functions to push arguments onto the stack, call a generic function pointer, obtain the return value and then restore the registers?

  • What issues to consider when rolling your own data-backend for Silverlight / AJAX on non-ASP.NET ser

    - by Edward Tanguay
    I have read-only Silverlight and AJAX apps which read static text and XML files from a PHP/Apache server, which works very nicely with features such as asynchronous loading, lazy-loading only what I need for each page, loading in the background, developed a little query language to get a PHP script to create custom XML files etc. it's pragmatic read-only REST, and all works fast and fine for read-only sites. Now I want to also add the ability to write data from these apps to a database on the same PHP/Apache server. For those of you who have built similar data-access layers, what do I need to consider while building this, especially regarding security so that not just any client can write and alter my database, e.g.: check HTTP_USER_AGENT for security check REMOTE_ADDR for security require a special code for security, perhaps a list of TAN codes (such as banks use for online transactions) each which can only be used once, both the client and server have these I wonder if there is some kind of standard REST query I should lean on for e.g. building SQL-like statements in the URL parameters, e.g. http://www.thedatalayersite.com/query?insertinto=customers&... Any thoughts, notes from experience, ideas, gotchas, especially ideas on tightening down security in this endeavor would be helpful.

  • Any book on designing and implementing a CRPG engine?

    - by Fabzter
    Hi! First, let me tell you, I am not really interested in making my own rpg engine (at least not in the near future, hehe), but I do feel like I want to understand the internals of how a rpg engine works. Why? Well, because I like to read about programming and design, It keeps me motivated and excited, and because I know I will learn a lot, for, even when I have been programming for some years now, I never stop considering myself an ignorant... there are simply SO many things involving a game engine (specially rpg ones, like branching storylines, and items and economics!) I'm eager to know. I've been searching (and thus, finding) lots of info online, but it is never focused in what I'm interested (most of it talks about the mathematics and AI algorithms implementation, which I know quite well), which is the design of overall structure, patterns, scripting engine, decision engine... damn, so many things I can't even imagine, since I've never done any game programming. I hope you know have an idea of how I feel, and how I want to learn for the sake of learning, and why would I want you to tell me if you know if there exist books touching the topics that interest me the most.

  • Update a PDF to include an encrypted, hidden, unique identifier?

    - by Dave Jarvis
    Background The idea is this: Person provides contact information for online book purchase Book, as a PDF, is marked with a unique hash Person downloads book PDF passwords are annoying and extremely easy to circumvent. The ideal process would be something like: Generate hash based on contact information Store contact information and hash in database Acquire book lock Update an "include" file with hash text Generate book as PDF (using pdflatex) Apply hash to book Release book lock Send email with book download link Technologies The following technologies can be used (other programming languages are possible, but libraries will likely be limited to those supplied by the host): C, Java, PHP LaTeX files PDF files Linux Question What programming techniques (or open source software) should I investigate to: Embed a unique hash (or other mark) to a PDF Create a collusion-attack resistant mark Develop a non-fragile (e.g., PDF -> EPS -> PDF still contains the mark) solution Research I have looked at the following possibilities: Steganography Natural Language Processing (NLP) Convert blank pages in PDF to images; mark those images; reassemble PDF LaTeX watermark package ImageMagick Steganograhy requires keeping a master copy of the images, and I'm not sure if the watermark would survive PDF -> EPS -> PDF, or other types of conversion. LaTeX creates an image cache, so any steganographic process would have to intercept that process somehow. NLP introduces grammatical errors. Inserting blank pages as images is immediately suspect; it is easy to replace suspicious blank pages. The LaTeX watermark package draws visible marks. ImageMagick draws visible marks. What other solutions are possible? Related Links http://www.tcpdf.org/ invisible watermarks in images Thank you!

  • Broken ssl, what to do

    - by TIT
    I have a site and i implemented ssl there. but when i browse it, the security seals dont come. i asked to godaddy, they replaid: Thank you for contacting online support. I cannot replicate the issue you have described. The error you described is caused by the way your site has been designed. If you receive this error, you have a combination of secure and non-secure objects on the page. For example, if your secure website was https://www.domain.tld and you added an object (an image, script, flash file, etc.) to that page that was located at http://www.domain.tld/image.jpg, you would break the seal. You will need to change your design to link to objects using https (ie https://www.domain.tld/image.jpg) or modify your site design to use relative paths (/image.jpg). This error can only be corrected by modifying your site design. Please contact your web designer or the manufacturer of your web design software if you require additional assistance modifying your site design. but the problem is i made everything,all my images javascripts are unders https, but the seal still not coming, saying: some content insecure. what is the problem.

  • Load Balancing of PHP/MYSQL script without big code changes

    - by DR.GEWA
    Sorry for my Dummy Question, but... I am making a script on php/mysql (codeigniter) and I am extremally interested in knowing if there is a way without big architectural changes of the script make a load balancing. I mean, that for example now I will rent a medium dedicated server with 2GB ram, 200GB memory and good processor, and this will be enough lets say half year for the users which will come. But when they will become more and more, and as its a social net and at nights the server is waiting to have 500-1500 or 5000-8000 users online, I wander if there is a way for lets say just add second server with some config which will bear next pressure. After again one and so on... ???? <? if($answer=YES) { how(??); } esle{ whatToDo(??); } ?> If there is no way, than maybe you could point to a easiest way of load balancing solution.... I will be extremally thanksfull if you can tell me for such purposes , should I move lets say to PostgreSQl or FireBird? Which of them will be more easy in the future to handle ? I am getting on the mysite.com/users/show/$userId page something like 60queries for all data... maybe too much, but anyway....after some optimization it can be 20-30....

  • Nginx rewrite for link shortener and Wordpress

    - by detusueno
    I'm a complete newbie to Nginx, so much so that I followed a online guide to do most of my server setup. I'm trying to learn but I'm still a ways away from understanding it all. So what I'm trying to create is a link shortener that redirects (example.com/x) to (example.com/short.php?id=x). Keep in mind that I'm also running a Wordpress blog on the same domain and plan on using the redirects/shortening for external links. The guide has so far had me add the following rewrites to enable Wordpress pretty URLs: # WordPress pretty URLs: (as per dominiek.com) if (-f $request_filename) { break; } if (-d $request_filename) { break; } rewrite ^(.+)$ /index.php?q=$1 last; # Enable nice permalinks for WordPress: (as per Yawn.it) error_page 404 = //index.php?q=$uri; And if it matters any, it was saved at (/usr/local/nginx/conf/wordpress_params.regular). Additionally, my Wordpress link structure adds "news" to all internal links (example.com/news/post-blah, example.com/news/category, ect.). What's the best way to tackle this setup?

  • Correct Interactive Website System Design Concepts / Methods?

    - by Xandel
    Hi all, I hope this question isn't too open ended, but a nudge in the right direction is all I need! I am currently building an online accounting system - the idea is that users can register, log in, and then create customers, generate invoices and other documents and eventually print / email those documents out. I am a Java programmer but unfortunately haven't had too much experience in web projects and their design concepts... This is what I have got thus far - A Tomcat web server which loads Spring. Spring handles my DAO's and required classes for the business logic. Tomcat serves JSP's containing the pages which make up the website. To make it interactive I have used JavaScript in the pages (jQuery and its AJAX calls) to send and receive JSON data (this is done by posting to a page which calls a handleAction() method in one of my classes). My question is, am I tackling this project in the right way? Am I using the right tools and methods? I understand there are literally countless ways of tackling any project but I would really love to get feedback with regards to tried and tested methods, general practices etc. Thanks in advance!

  • Delphi 6 OleServer.pas Invoke memory leak

    - by Mike Davis
    There's a bug in delphi 6 which you can find some reference online for when you import a tlb the order of the parameters in an event invocation is reversed. It is reversed once in the imported header and once in TServerEventDIspatch.Invoke. you can find more information about it here: http://cc.embarcadero.com/Item/16496 somewhat related to this issue there appears to be a memory leak in TServerEventDispatch.Invoke with a parameter of a Variant of type Var_Array (maybe others, but this is the more obvious one i could see). The invoke code copies the args into a VarArray to be passed to the event handler and then copies the VarArray back to the args after the call, relevant code pasted below: // Set our array to appropriate length SetLength(VarArray, ParamCount); // Copy over data for I := Low(VarArray) to High(VarArray) do VarArray[I] := OleVariant(TDispParams(Params).rgvarg^[I]); // Invoke Server proxy class if FServer <> nil then FServer.InvokeEvent(DispID, VarArray); // Copy data back for I := Low(VarArray) to High(VarArray) do OleVariant(TDispParams(Params).rgvarg^[I]) := VarArray[I]; // Clean array SetLength(VarArray, 0); There are some obvious work-arounds in my case: if i skip the copying back in case of a VarArray parameter it fixes the leak. to not change the functionality i thought i should copy the data in the array instead of the variant back to the params but that can get complicated since it can hold other variants and seems to me that would need to be done recursively. Since a change in OleServer will have a ripple effect i want to make sure my change here is strictly correct. can anyone shed some light on exactly why memory is being leaked here? I can't seem to look up the callstack any lower than TServerEventDIspatch.Invoke (why is that?) I imagine that in the process of copying the Variant holding the VarArray back to the param list it added a reference to the array thus not allowing it to be release as normal but that's just a rough guess and i can't track down the code to back it up. Maybe someone with a better understanding of all this could shed some light?

  • Why can't I pass an argument to create this window using wxpython?

    - by somefreakingguy
    I am trying to learn how to make a GUI in python! Following an online tutorial, I found that the following code 'works' in creating an empty window: import wx from sys import argv class bucky(wx.Frame): def __init__(self, parent, id): wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(300, 200)) if __name__=='__main__': app=wx.PySimpleApp() frame=bucky(parent=None,id=-1) frame.Show() app.MainLoop() That gives me a window, which is great. However, what if I want to get an argument passed onto the program to determine the window size? I thought something like this ought to do the trick: import wx from sys import argv script, x, y = argv class mywindow(wx.Frame): def __init__(self, parent, id): wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(x, y)) if __name__=='__main__': app=wx.PySimpleApp() frame=mywindow(parent=None,id=-1) frame.Show() app.MainLoop() But, alas, that does not work! Nor does the raw_input() function pass on the value. I keep getting the following error: C:/Python26/pythonw.exe -u "C:/Documents and Settings/Owner/Desktop/wz.py" File "C:/Documents and Settings/Owner/Desktop/wz.py", line 8 wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(x y)) ^ SyntaxError: invalid syntax Thanks for the help!

  • Can someone copyright an SQL query?

    - by Samutz
    I work for a school district. Every year we have to export a list of students from our student management system and send it to a company that handles our online exams. So to do this export, we had to hire someone who knew the inner workings of our student management system. He wrote an sql (Adaptive Sybase SQL Anywhere) query to export the students to a csv file like we needed. This was before I started working for the district, so for a while I assumed this was an actually application, until it came time for me to do the export myself. And every year he charges us $500 to update this query to export the students for the current year. So when I discovered it was only a query (.bat file and .sql file), my thought was "I can update this myself". All I have to do is change the years in the query (eg. 2009 to 2010). The query (.sql file) itself has this comment at the top: // This code was writtend by [the guy] // and is the property of [his company]...Copyright 2005,2006,2008,2009 // This code MAY NOT BE USED without the expressed written consent of // [his company]. (Yes, it really does says "writtend".) So now my boss is worried that we're violating the copyright. And that the guy is gonna find out that I updated the query myself because we haven't asked him to update it this year and take legal action. So back to the subject's question: Can he really copyright this query? And if so, is modifying it ourselves a copyright violation? In my mind, a single query isn't program code. It's more a command line command. But I don't know what it's considered legally.

  • Fast sign in C++ float...are there any platform dependencies in this code?

    - by Patrick Niedzielski
    Searching online, I have found the following routine for calculating the sign of a float in IEEE format. This could easily be extended to a double, too. // returns 1.0f for positive floats, -1.0f for negative floats, 0.0f for zero inline float fast_sign(float f) { if (((int&)f & 0x7FFFFFFF)==0) return 0.f; // test exponent & mantissa bits: is input zero? else { float r = 1.0f; (int&)r |= ((int&)f & 0x80000000); // mask sign bit in f, set it in r if necessary return r; } } (Source: ``Fast sign for 32 bit floats'', Peter Schoffhauzer) I am weary to use this routine, though, because of the bit binary operations. I need my code to work on machines with different byte orders, but I am not sure how much of this the IEEE standard specifies, as I couldn't find the most recent version, published this year. Can someone tell me if this will work, regardless of the byte order of the machine? Thanks, Patrick

  • Dot Matrix printing in C# ?

    - by Dale
    I'm trying to print to Dot Matrix printers (various models) out of C#, currently I'm using Win32 API (you can find alot of examples online) calls to send escape codes directly to the printer out of my C# application. This works great, but... My problem is because I'm generating the escape codes and not relying on the windows print system the printouts can't be sent to any "normal" printers or to things like PDF print drivers. (This is now causing a problem as we're trying to use the application on a 2008 Terminal Server using Easy Print [Which is XPS based]) The question is: How can I print formatted documents (invoices on pre-printed stationary) to Dot Matrix printers (Epson, Oki and Panasonic... various models) out of C# not using direct printing, escape codes etc. **Just to clarify, I'm trying things like GDI+ (System.Drawing.Printing) but the problem is that its very hard, to get things to line up like the old code did. (The old code sent the characters direct to the printer bypassing the windows driver.) Any suggestions how things could be improved so that they could use GDI+ but still line up like the old code did?

  • Silverlight databinding error

    - by Petezah
    I found an example online that explains how to perform databinding to a ListBox control using LINQ in WPF. The example works fine but when I replicate the same code in Silverlight it doesn't work. Is there a fundamental difference between Silverlight and WPF that I'm not aware of? Here is an Example of the XAML: <ListBox x:Name="listBox1"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Name}" FontSize="18"/> <TextBlock Text="{Binding Role}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> Here is an example of my code behind: private void UserControl_Loaded(object sender, RoutedEventArgs e) { string[] names = new string[] { "Captain Avatar", "Derek Wildstar", "Queen Starsha" }; string[] roles = new string[] { "Hero", "Captain", "Queen of Iscandar" }; listBox1.ItemSource = from n in names from r in roles select new { Name = n, Role = r} }

    I have an online flash application that acts as a front end for a server application built in delphi. The server can be installed/used on a remote computer or a personal version can be downloaded and the Flash app pointed at localhost to use it. However, Flash has issues with using the POST and GET functions on the localhost, which makes uploading data files and downloading results files difficult. To get past the difficulty with downloading results files I'm planning to just have the server app serve the results file as an attachment and have the Flash app open the address of the file up in another browser window using external interface. First off, is this likely to cause similar security issues? I.E. Flash will see "localhost" in the external interface call and stop it from working the same as when I try to use POST/GET functions with localhost? Secondly, for upload this seems just a bit little trickier, I'm planning on doing something similar, having flash use external interface to open a php script for a file upload. Is this feasible and, again, will Flash still have security issues? Lastly, if anyone knows how to get flash to execute POST and GET functions with localhost addresses, I'd love to have that information to avoid all this jumping through hoops.

  • How to gray out HTML form inputs?

    - by typoknig
    What is the best way to gray out text inputs on an HTML form? I need the inputs to be grayed out when a user checks a check box. Do I have to use JavaScript for this (not very familiar with JScript) or can I use PHP (which I am more familiar with)? EDIT: After some reading I have got a little bit of code, but it is giving me problems. For some reason I cannot get my script to work based on the state of the form input (enabled or disabled) or the state of my checkbox (checked or unchecked), but my script works fine when I base it on the values of the form inputs. I have written my code exactly like several examples online (mainly this one) but to no avail. None of the stuff that is commented out will work. What am I doing wrong here? <label>Mailing address same as residental address</label> <input name="checkbox" onclick="disable_enable() "type="checkbox" style="width:15px"/><br/><br/> <script type="text/javascript"> function disable_enable(){ if (document.form.mail_street_address.value==1) document.form.mail_street_address.value=0; //document.form.mail_street_address.disabled=true; //document.form.mail_city.disabled=true; //document.form.mail_state.disabled=true; //document.form.mail_zip.disabled=true; else document.form.mail_street_address.value=1; //document.form.mail_street.disabled=false; //document.form.mail_city.disabled=false; //document.form.mail_state.disabled=false; //document.form.mail_zip.disabled=false; } </script>

  • TranslateTransform for drag and drop in Silverlight

    - by fuzzyman
    We're trying to implement drag and drop in Silverlight (3). We want users to be able to drag elements from a treeview onto another part of a UI. The parent element is a Grid, and we've been trying to use a TranslateTransform along with the MouseLeftButtonDown, MouseMove (etc) events, as recommended by various online examples. For example: http://www.85turns.com/2008/08/13/drag-and-drop-silverlight-example/ We're doing this in IronPython, but that should be more or less irrelevant. The drag start is correctly initiated, but the item we are dragging appears in the 'wrong' location (offset a few hundred pixels to the right and down from the cursor) and I can't for the life of me work out why. Basic xaml: <Grid x:Name="layout_root"> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition Height="120"/> </Grid.RowDefinitions> <Border x:Name="drag" Background="LightGray" Width="40" Height="15" Visibility="Collapsed" Canvas.ZIndex="10"> <Border.RenderTransform> <TranslateTransform x:Name="transform" X="0" Y="0" /> </Border.RenderTransform> <TextBlock x:Name="dragText" TextAlignment="Center" Foreground="Gray" Text="foo" /> </Border> ... </Grid> The startDrag method is triggered by the MouseLeftButtonDown event (on a TextBlock in a TreeViewItem.Header). onDrag is triggered by MouseMove. In the following code self.root is Application.Current.RootVisual (top level UI element from app.xaml): def startDrag(self, sender, event): self.root.drag.Visibility = Visibility.Visible self.root.dragText.Text = sender.Text position = event.GetPosition(self.root.drag.Parent) self.root.drag.transform.X = position.X self.root.drag.transform.Y = position.Y self.root.CaptureMouse() self._captured = True def onDrag(self, sender, event): if self._captured: position = event.GetPosition(self.root.drag.Parent) self.root.drag.transform.X = position.X self.root.drag.transform.Y = position.Y The dragged item follows the mouse move, but is offset considerably. Any idea what I am doing wrong and how to correct it?
